Acoustic emission source location using multi-frequency arrival times
In this paper, a method for a direct estimation of the source-sensor distances and the time of an acoustic emission event is presented using multiple sensors and the arrival-times for a certain number of frequencies. The mean square error (MSE) problem is solved directly for any set of available data. It is also proved that in case of error-free arrival-times, the source position can be derived analytically as a function of the material constant
